J found this on a vacation day that was devoted to hiking and caching. I found this one between the two parts of the Operation cache. I saw the empty nest that JC detached, and took a little while to find the cool container that I was not expecting (but in hindsight I should have). The second part was my favorite because of the search method. I have never found an offset before, and did not know my GPSr could even do this until I dug around the menus! And while I have had kidney stones before, I was not scared by the title of this cache.
